Question

我面对这样的错误：

Caused by: javax.xml.bind.UnmarshalException: unexpected element (uri:"http://xmlns.jcp.org/xml/ns/persistence", local:"persistence"). Expected elements are <{http://java.sun.com/xml/ns/persistence}persistence>
        at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallingContext.handleEvent(UnmarshallingContext.java:740)
        at com.sun.xml.bind.v2.runtime.unmarshaller.Loader.reportError(Loader.java:262)

我正在尝试构建一个简单的osgi jpa 2.1 模块，该模块将在Glassfish 4.1上运行并使用Postgres 9.4。 GF上的JDBC资源已经创建并且工作正常（我的意思是“ping”按钮），以及在META-INF目录上写一个persistence.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="something" transaction-type="JTA">
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <jta-data-source>jdbc/myjdbc</jta-data-source>
        <properties>
            <property name="javax.persistence.schema-genaration" value="drop-and-create"/>
        </properties>
    </persistence-unit>
</persistence>

最有趣的是 - 如果我将jpa 2.1模式替换为jpa 2.0，它将正常工作，但只能无法从实体类创建表。

那么，如何解决这个问题并使用JPA 2.1 xml架构。

Add.information：

新闻实体在这里：

@Entity
public class News {

    @Id
    @GeneratedValue
    private Long ID;
    private String title;
    private String content;
    private Long views;

    // getters and setters.... default non-arg constructor was omitted
